Chapter 6:
RAW WATER SYSTEM
6.1 General
In the raw or seawater systems, all water 12-volt pumps are
supplied by hoses connected to ball valves and thru hull fit-
tings located in the bilge below the cockpit. Always make
sure the ball valves are open before attempting to operate any
component of the raw water system.
The optional air conditioner uses a 120-volt AC seawater sup-
ply pump. The ball valve for this pump is in the bilge. This
is the only 120-volt pump in the raw water system and it is
automatically activated when the air conditioning or heating
system is in use.
Priming the System
Make sure the ball valves are open. Open the faucet on the
raw water washdown and activate the pressure pump by turning
the Washdown switch in the helm switch panel to the “ON”
position. Run the pump until all of the air is purged from the
system and then turn the faucet off. As the pressure builds, the
pump will automatically shut off. Activate the livewell pump
by turning the Aerator switch to the “ON” position. Run the
pump until all of the air is purged from the system and then turn
the switch off. If the shore power is connected and activated,
turn on the optional air conditioner and monitor the discharge
fitting for the air conditioning water pump. Water should begin
to flow from the discharge fitting within 30 seconds. If water
does not flow, the system may have an air lock or debris in
the strainer and will automatically shut down. Investigate and
correct the problem, then restart the air conditioner. All raw
water systems will now be primed.
The intake for the air conditioner raw water pump is equipped
with a scoop and ball valve. If the pump runs but will not prime
after cleaning the strainer or at the time of launching, make
sure the valve is open. If the pump still won’t prime, it may
be air locked. Make sure the valve is open and run the boat at
or above 15 M.P.H. The water pressure from the scoop will
force the trapped air through the pump and allow it to prime.
If this procedure doesn’t work, contact your Scout dealer or
Scout Customer Service.
Closing the thru-hull ball valves before the boat is hauled
from the water will help to eliminate air locks in raw water
systems.
Note: It may be necessary to reprime the raw water sys-
tem if it has not been used for an extended period
and at the time of launching.
DO NOT ALLOW THE WATER PUMP TO RUN DRY.
THE PUMP WORKS ON DEMAND AND WILL NOT
S H U T O F F AU TO MAT I C A L LY I F N O WAT E R I S
AVAILABLE. THIS CAN RESULT IN DAMAGE TO
THE PUMP. ALWAYS TURN THE WASH DOWN
SWITCH OFF WHEN THE RAW WATER SYSTEM IS
NOT IN USE.
6.2 High Pressure Washdown
A 12-volt high pressure pump, controlled by a pressure sensor,
supplies the raw water hose connector located in the cockpit.
The pump is activated by the Washdown switch located in the
helm switch panel. The switch should be turned to the “ON”
position just before using the washdown and be turned to the
“OFF” position when the washdown is not in use.
When activated, the pressure switch will automatically control
the pump. As the pressure builds in the supply hose, the pump
will shut off. When the washdown hose is in use and the pres-
sure drops, the pump will turn on.
